To all whom it may concern: I

, 'Be it known that I, LUIS W. Pnonenm a citizen of the UnitedStates; and resident of Pittsburgh, in the county of Allegheny. and

full, clear; and .exactdescriptionfthereof;

ufacturing bottles or other glass articles.

manufacturing, morepar ticu-larly narrow neck bottles, the machine being entirely automatic, and the operations of forming the. fblanknnd blowing the-Ebottlefoliowing in quicksuccession, so that no-time is lost and the capacity of the machine will be very high. y

. It is impossible in a general way to enu-' merate iin-the premises the numerous fea tures of novelty involved in my. machineand ll will therefore 're fer those skilled in the art] to the following specification and claims for a full understanding of'my invention.

In the accompanying-drawings Figure- 1 is a plan view of my improved machine;

Fig. 2 is a section on the line 22 Fig. 1; Fig. 3 is a 'sectionon the line 33 Fig. 1; Fig. 4: is a section on the line" 4-4 Fig. 3; Fig. 5 is a plan View of the mechanism for imparting an intermittent movement to the machine; Fig. 6 is a detail of the cam mech-.

Figs. 15 and. 16 are detail views of blowing valves.

Referring to the drawings the numeral 2 designates a sui'uklihle' baseo-r platformwhich may be mountediion Wheels-so. that the machine may be easily transferred from one part of the factory to the other. Stepped 5 in the base 2 is the column or shaft 3. The

My invention relates to machines for man-- umn 3," andbolted or otherwise. secured to said hollowshaft 4e isjthe plateor table "5. The table -5 "rests upon the pedestal 6 on the base 2 andthe ball-bearings 7 are interposed between said pedestal and the table 5 to facilitatethe rotary movement of said table-J I Secured to the'lqw'er face-of thetable 5 is the star-wheel -8 which has the radialigrooves 9.- The segment 10 is mounted on the shaft 11 and the arm 12 of. said segment has the :stud orrro'ller 13 which isadapted to engage the radial :grooves;9 to impart an interm te tent movement to the table 5, as fully hereinafter set forth. The curved portion of the segment 10 will fit within the depressions 14.-

of-the star-wheel 8 when the roller 13 is not n engagement with one of .the grooves so as to block or preventthe radial movementfOf; said star-wheel.

The shaft 11 is mounted in bearings 15 in the base 2 and to the lower end ofsaid shaft is secured the gear-wheel 16. This gear wheel 16 is engaged by the gear-wheel 17 on'the vertical shaft 18. worm-wheel 19 on the shaft 18 is engagedby aaworm 20 mounted on the upright 21. In this manner:

power is transmitted from the Worm;shaft 20 through the intermediate gears to rotate the segments 10 and through it impart :an

intermittent movement tothe table 5.

The blow-mo'1ds22 are carried on the table from the center. of said guideplate one for Zeaeh blow mold. The slidi block '27" is- :further provided with the :stii

which engages thex cam-way '33 in z-the. stabolted or otherwise secured to the rota y hollow shaft 4 and the grooves 29 red ateor. roller 32 tionary cam 34; ="Phis cam 34- is.held station a ry by being secured to the casting 35,said casting being bo tedio'rr otherwise-secured to the arms 36. The arms-36 extend iou't and are connected to thefstht-ionary-frime 37,.

- said arms being arranged so as inter.-

fere with any oftheparts during movement of'themolds. I The casting-35 has at its upper end the camwayi38 which operates iii lconnection with the cam 39 carried by one of its sta- I tiona'ryarms 36. The cam 39has the cam way 40 which is parallel with the cam-way 38. The short racks 41' and 42 are secured to the casting 35 at certain positions with referenceto the cam-way 38 for the purpose more fullvhereinafter set forth. A cam-guide 43 is bolted or otherwise secured to the casting 35 and the guide 44 is secured to the cam 39.

' The hollow-shaft 4 is provided with the vertical" guide-ways Short sleeves 46 are provided with the heads'47 which are adapted'to engage theguide-ways 45 so that said sleeves are adapted to move up and down in said guide-ways and are supported against outward movement by the plates 48 engaging said heads 47'. The shafts 49 are inserted in the sleeves'46 and are held therein by the set-screws 50 as clearly shown in .Fig. 8. Bevel-rollers 51 are-loosely mounted on the shafts 49, and said rollers are adapted to rest upon and travel on the cam-way 38. Beyond the rollers 51 are the sleeves 52 which are loosely mounted on the shafts 49 and bevel-gears 53 are carried by the sleeves 52. The sleeves 52 havev the yokes 54 which are connected to the links 55 the outer ends of said links being connected to the lugs 56 on the halves of the neck-mold 57. The halves of the neck-mold are connected by the vertical pins 58 and said pins also pass down through the lugs 59 on the swivel 60, said swivel being mounted on the shaft 49.- V

The sleeves 52 are provided with the studs for rollers 61 which are adapted to engage the cam-way 62- carried by the casting35 for the purpose of opening the neck-mold asfully hereinafter set forth.-

The'neck-mold 57 'is provided with latch 63which is pivoted at 63, said latchwhen thrown to the horizontal position engaging the pin 64 on one of the halves of the neck-mold A pin 65 actsas a stop for the other end of the latch. This latch i operated automatically by the fingers 66 and 67. which are in the path of the move- 'ment of. 'theneclemold at positions indicated in Fig.. 4 for locking and unlocking the neck-mold as fully hereinafter'set forth. At the upper'end of the hollow sleeve 4 and secured thereto is the spider 68. This spider carries at the outer end of its arms the blank-molds 69; The halves of-the' blankmolds are connected by the pins 70 and said blank-molds are opened and closed by" the same form of mechanism as indicated in Fig. 9 inconnection with the blow-mold. i'he guide-plate 71 corresponds to the guideplate 30 and the lugs 72 engage with the grooves in said guide-plate 71. The yoke 73 is connected totheguide-lug 72 and said yoke is connected at its ends by links 74 to theiinold-halvesq A. stud or roller 75 (111- extending web is admitted to the upper end of the cylinder 81 to act on the plunger 83' to lower the .piston 82. Connected to the piston-rod 84 is the closure or cap which closes one end of the blank-mold. Air is admitted by the pipe 86 which passes down through the cap 85 into the mold.

Secured to the piston-rod 84 is the collar 87 and said collar carries the fork 88, which,

when the piston-rod is lowered, is adapted to engage the lugs 89 on the halves of the .mold andsov lock and hold the mold halves securely together.

. The cylinder'90 is supported by the upright and within said cylinder is the piston '9l. A pipe 92 admits air to said cylinder to move the-plunger 93. A pistonrod 94 is connected to'the piston 91 and an arm 95 on said piston-rod carries the small cylinder 96. The plunger 97 is contained within the cylinder 96 and said plunger has the stem 98 which has the tapering tip 99. The'stem 98 of the'plunger enters the chamber 100 in the plug 101. A pipe 102 delivers air to this chamber 100. The plug 101 lifted by the piston 91 so as to enter the' tapering seat 103 in the neck-mold, as clearly indicated in Fig. 2.

The upright 104 has the arm 105 which i carries the cylinder 106. An arm 107 is connected to the piston of this cylinder and said arm carries the cap or closure. 108. v The pipe 10 9-admits air to the cap for the blowing operation. In Fig. 15 I have illustrated in detail the mannerin which the air is admitted to blow the bottle. The tubular connection 110 enters the cap'108 and a sleeve 111 engages the shoulder 112 on said tubular connection, there beinga space 113 left between the lower end of said tubular connection and the inner bottom face. of the cap 108. Contained within the connection is the valve-stem 114 which has the valve 115 which rests on the seat .116. Below the valve 115 is the extension 117 with radially ortions which rests on the inner bottom ace of the cap .108. The upper end of the stem 114 has the webbed extension 118, which is slightly separated from the upper end of the connection 110 leaving the space 119. A slight depression or cavity 120 is also formed in the lower end of *the connection 110. Air ports 121 are formed in the cap .108 for the purpose fully.

hereinafter set forth.

A cylinder 122 is provided to operate the iii ea ers mold on the table below and in line therewith'will be open. The necessary amount of glass at the proper consistency for blowing.

is introduced in any suit-able manner into the opening of the neck-mold, When the glass has been so introduced,,the rotary-frame,

which is intermittently operated by the segment engaging one of the grooves 9 of the star-wheel the blank-mold and neck-- mold, will be moved from the charging position to the next osition where the neck is formed and the lank prepared forthe blowing operation. The mold in this position is clearly shown in Fig. 2 where the'air has been admitted to the cylinder 81 to lower w and passes down through the closure or capthe closure 85 down into the-open end of theblank-mold 69 while atlthe same time air is admitted to the cylinder 90 to lift the arm 95 and theplug 103 up into the neck-mold 57. Air is then admitted by the pipe 86,

85 into the blank-mold where the pressure of the air tends to force the glassdown with-v in the mold to fill'up the cavities of the neckmoldcompactly, so as to form aperfeot neck within the neck-mold. At .thesame time that the closure is lowered into the blank-mold the lock 88 is also lowered and engages the lugs ,85 so as to'lock the blanks mold securely. Air is now admitted to the lower end of the cylinder 81 to raise the closure 85 and at the same time unlock the mold, while at the same timeair is admitted bythe pipe, but previous to this movement of the closure the air is withdrawn from the cylinder 96 to allow theplunger 98 to be lowered to the position connected in dotted lines Fig. 16. This lowering of the plunger 98 will open the port in the plug 101 and air can pass through the pipe 102 aroundthe -tapering tips 99 of the plunger 98 and this air so admitted will act to form a slight cavity in the neck end of'the blank mold as indicated in dotted lines Fig. 2. The plug 103 is then lowered by releasing the air from the cylinder and at this stage in the op' eration the rotary-frame once more rotates and the roller 75 passes into that portion of the cam-way 7 6 which willdraw' the roller toward the center of the cam, the block-72 lmovingin the radial guide in the guide plate 71. This will acttoiopen the blank-mold. and just as soon as the blank-mold is openedfthe bevel-gear 53 of the neck-mold by which the blank is carried will engagethe rack 41, the roller 51 at the same time the table 5.

- form, as shown in Fig. 3. When th' bottle'has been blownin this descendin the cam-way 38. This engagement of t e bevel-gear 53' with the rack 41 will act to turn the neck-mold on its swivel 60, the sleeve 52 turning on the shaft49. This inverting of the neck-mold will bring the blank carried thereby into its upright position where it is received by theopen blow-mold in line therewith and belowon The undue elongation or stretching-of the blank in this transfer from the blankemold to the blow-mold is pre--- vented by the fact that in the turning of the blank-in movingfrom its upright position in the blank-mold to a like position in the blow-mold is at the same time moving in the same. direction as the machine, and consequently the efi'ect of the centrifugal force in the rotatin of the blank is practically eliminated, and is-lowered from the level of the-blank-mold at the same time the blank" to the level of the blow-m1old by the travel v of the bevel-wheel 51 down the incline of the cam-way 38. The guides 43 and 44 are engaged by the roller 53 in its descent so that it is properly guided.

the neck-mold and inverted by the action '90. As stated above the blank thus'carried byv of the cam-way 38 is brought down. in po- 4 sition to be engaged bythe blow-mold and just as soon as the blank is positioned in the blow-mold the cam 34, by the engagement of its cam-way 33 with the'stud or roller 32, will act to close the blow-mold around the blank, as indicated in Fig. 4. At this stage in the operation the rotary frame -again comes to a standstill and the blowing of the bottle in the blow-mold then takes place.

As soon .as the rotary frame comes" to a state of rest, air is admitted to the cylinder 106 and the closure orv cap 108 is lowered as indo'wnward movement of the. arm 107' will force the connection down until it'stiikes atv dicated in Fig. 15.- When the closure 108 "has been seated in this way,. the further air admitted by the pipe 109 will pass down-- through the'valve and by the ports12l-intoto the finished the blank to blow the bottle manner the air is admitted to thecy'linder.

105 to raise the arm 107 and the closure can ried thereby, but before the closure rises the connection 110 will be lifted soias to cutoff. the supply of air to the bottle, "and upon a furthermovement of the arm 107 the closure; will be lifted. As soon asthe closure has been lifted the rotary motion is. again im- 62 and theLneck-mold will be opened as "Tclearly shown in Fig. {L At this point' the Kmachine again comesto a stand-still and the finished bottle is removed from the opened blow-mold and neck-mold, and on the next movement of the machine the neck-mold is closed by the action of the. cam-way 62 and the neck-mold is locked by the latch 62" coming into engagement. with the finger 67 with the neck-mold in this closed position. The bevelgearnow engages the rack 42 of the cam 38 and as the neckqnold ascends the cam,"it is turned by the action ofthe rack 42fand it continues on np the cam-way 39 until it is'brought to a horizontal position whence it travels around until it again arrives at the charg- 'ing position where the operation just de- I bring said neck-mold into operative position int'he same direction in which said rotary frame 18 moved to brin g saidneck-mold into scribed is repeated. It is,-'of course, to be understood that while we have followed the movements of one neck-mold in the operation ofmaking a bottle, that the other neck-moldsjhave each been going through the sameoperations so that each time the machine makes one of its intermittent-move ments a bottle is finished,
